|Physics I- Classical Mechanics - Rigid Body Dynamics- Rotation and Translation About a Fixed Axis - Peter Dourmashkin|
We shall analyze the motion of systems of particles and rigid bodies that are undergoing translational and rotational motion. There is no longer a clearly fixed axis of rotation but we shall see that is possible to describe the motion by a translation of the center of mass and a rotation about the center of mass. By choosing a reference frame moving with the center of mass, we can analyze the rotational motion and discover that the torque about the center of mass is equal to the change in the an...

|Development of a Method for Local Electron Temperature and Density Measurements in the Divertor of the JET Tokamak - Jupen, C.|
Plasma volume recombination in the divertor, a process in which charged particles recombine to neutral atoms, contributes to plasma detachment and hence cooling at the divertor target region. Detachment has been observed at JET and other tokamaks and is known to occur at low electron temperatures (T(sub e))1 eV) and at high electron density (n(sub e)10(exp 20)/m(exp 3)). The ability to measure such low temperatures is therefore of interest for modelling the divertor...

|Chemical approach for controlling nadimide cure temperature and rate - NON|
Polyimide resins suitable for use as composite matrix materials are formed by copolymerization of maleic and norbornenyl endcapped monomers and oligomers. The copolymers can be cured at temperatures under about 300 C by controlling the available concentration of the maleic endcapped reactant. This control is achieved by adding sufficient amounts of said maleic reactant or by chemical modification of either copolymer, to either increase Diels-Alder retrogression of the norbornenyl capped reactant...

Sodium chloride is deposited on the surface of alumina substrates and exposed to air containing 1% SO2 at temperatures between 500 C and 700 C. In all cases the sodium chloride was converted to sodium sulfate. The volatilization of sodium chloride from the original salt particles was responsible for the development of a uniform coating of sodium sulfate on the alumina substrate. At temperatures above 625 C, a liquid NaCl-Na2SO4 autectic was formed on the substrate...
